Active Ingredient (A.I.):
bentazon
Common product name:
Basagran; Basagran T/O
|
Rate -
(broadcast) 16 - 32 fl oz/A (0.5 - 1 lb a.e./A)
(spot) Equivalent to broadcast rates.
Timing -
Apply to rosettes in fall or spring to bolting plants.
Caution -
Do not apply directly to water or to areas where surface water is present. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants.

Active Ingredient (A.I.):
glyphosate
Common product name:
Roundup Pro; many others (Aquatic: Rodeo; AquaNeat)
|
Rate -
(broadcast) 0.75 - 1.5 lb a.e./A
(spot) For a 3 lb a.e./gal product. 1 - 3% (0.03 - 0.09 lb a.e./gal)
Timing -
Apply to rosettes in fall or spring, bolting, or flowering plants. Use higher rates when air or soil temperatures drop below 40°F to maintain control.
Remarks -
Fall applications will only control rosettes and will not control seedlings that emerge in the spring.
Caution -
Use product labeled for aquatic use if potential exists for solution to contact surface waters. Applications can result in bare ground as glyphosate is not selective. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants.

Active Ingredient (A.I.):
imazapic
Common product name:
Plateau
|
Rate -
(broadcast) 10 - 16 fl oz/A (0.15 - 0.24 lb a.e./A)
(spot) 0.25 - 1% (0.005 - 0.02 lb a.e./gal)
Timing -
Apply to rosettes in the fall or spring or to bolting plants.
Caution -
Do not apply directly to water or to areas where surface water is present. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. Imazapic can remain in the soil for months depending on application rate and has the potential to contaminate surface runoff water during this timeframe. Maintenance of a vegetative buffer strip is recommended between the areas Imazapic is applied and surface water features. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants.

Active Ingredient (A.I.):
imazapic + glyphosate
Common product name:
Journey

Rate -
(broadcast) 8 fl oz/A (imazapic: 0.05 lb a.e./A + glyphosate: 0.9 lb a.e./A
(spot) 0.6 - 2.4% (imazapic: 0.005 - 0.02 lb a.e./gal + glyphosate: 0.009 - 0.04 lb a.e./gal)
Timing -
Apply to rosettes in the fall or spring or to bolting plants.
Caution -
Do not apply directly to water or to areas where surface water is present. Applications can result in bare ground as glyphosate is not selective.

Active Ingredient (A.I.):
imazapyr
Common product name:
Arsenal; Stalker (Aquatic: Habitat; Imazapyr 2sl)

Rate -
(broadcast) 48 - 64 fl oz/A (0.75 - 1.0 lb a.e./A)
(spot) 0.5 - 1% (0.01 - 0.02 lb a.e./gal)
Timing -
Apply to rosettes in the fall or spring or to bolting plants.
Caution -
Use product labeled for aquatic use if potential exists for solution to contact surface waters. Applications can result in bare ground as imazapyr is not selective and can remain in the soil for several months to over a year depending on application rate. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants.

Active Ingredient (A.I.):
metsulfuron
Common product name:
Escort XP; Ally XP
|
Rate -
(broadcast) 0.25 - 1 oz/A (0.15 - 0.6 oz a.i./A)
(spot) 0.04 oz/gal (0.02 oz a.i./gal)
Timing -
Apply to rosettes in the fall or spring or to bolting plants.
Remarks -
Use lowest rate in spring. In fall use 0.5 - 1 oz/A to provide residual control of seedlings the following spring. Use higher rates in high organic matter soils.
Caution -
Do not apply directly to water or to areas where surface water is present. Remains in the soil for months depending on application rate. Overspray or drift to desirable plants should be avoided as even minute quantities of the spray may cause severe injury to plants.

Active Ingredient (A.I.):
sulfometuron
Common product name:
Oust; Spyder
|
Rate -
(broadcast) 0.25 - 1 oz/A (0.2 - 0.75 oz a.i./A)
(spot) Equivalent to broadcast rates.
Timing -
Apply to rosettes in the fall or spring or to bolting plants.
Remarks -
Use 0.25 - 0.5 oz/A in spring. In fall use 0.5 - 1 oz/A to provide residual control of seedlings the following spring. Use higher rates in high organic matter soils.
Caution -
Do not apply directly to water or to areas where surface water is present. Applications can result in bare ground as sulfometuron is not selective and can remain in the soil for months depending on application rate and site conditions. Overspray or drift to desirable plants should be avoided as even minute quantities of the spray may cause severe injury to plants.

Fall applications will only control rosettes and will not control seedlings that emerge in the spring.
Caution -
Use product labeled for aquatic use if potential exists for solution to contact surface waters. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. Overspray or drift to desirable plants should be avoided as even minute quantities of the spray may cause severe injury to plants.

Active Ingredient (A.I.):
aminocyclopyrachlor + metsulfuron
Common product name:
Streamline
|
Rate -
(broadcast) 4.75 - 9.5 oz/A (aminocyclopyrachlor: 1.9 - 3.75 oz a.i./A + metsulfuron:0.6 - 1.2 oz a.i./A)
(spot) 0.2 - 0.4 oz/gal (aminocyclopyrachlor: 0.08 - 0.16 oz a.i./gal + metsulfuron:0.03 - 0.05 oz a.i./gal)
Timing -
Apply to rosettes in the fall or spring or to bolting plants.
Caution -
Do not apply directly to water or to areas where surface water is present. Avoid using Streamline in areas where soils are permeable, particularly where the water table is shallow as groundwater contamination may result. Streamline remains in the soil for months depending on application rate and has the potential to contaminate surface runoff water, especially on poorly draining soils or areas with shallow groundwater. Maintenance of a vegetative buffer strip is recommended between the areas Streamline is applied and surface water features. Overspray or drift to desirable plants should be avoided, as even minute quantities of the spray may cause severe injury to plants. Do not compost treated plants as herbicide can persist through composting process.
